Underwater Reactor

FINAL FANTASY VII guide · Retrieving the Huge Materia from the ocean floor

Cloud and the party infiltrate the underwater Mako reactor beneath Junon to stop Shinra from loading the third Huge Materia onto a submarine. After descending through an elevator and a glass ocean tunnel, you fight through reactor docks, confront Reno, and defeat the mechanical boss Carry Armor. Once victorious, you commandeer a red submarine, complete an underwater torpedo minigame, and secure the Huge Materia.

Tips

Focus all single-target attacks on Carry Armor's main body or quickly destroy its arms using powerful Lightning or magic attacks before both of your companions get held captive.
Equipping the Morph Materia allows you to morph the Ghost Ship enemy into a Guide Book, which can later be traded in Kalm for the Underwater Materia.
You cannot return to the submarine docks once you complete the submarine battle, so be sure to open every treasure chest along the catwalks before boarding the vessel.
